The ±10 ppm frequency stability holds the timing budget for most 1 GbE and CPRI links; a ±25 ppm part would risk bit errors over temperature and aging, so this grade is the right fit for a link that must run at the line rate without retraining. ## Active production — no end-of-life scramble It is orderable today and supported for new designs — no last-time-buy window to track, no successor migration to plan. ## Package and supply — what the board sees 6-SMD no-lead package, 3.20 mm x 2.50 mm footprint, 0.90 mm seated height. Operating temperature range -20°C to 70°C covers indoor equipment and most outdoor telecom cabinets with passive cooling; for an engine-bay or downhole application, a wider-temperature variant from the DSC1122 family would be needed.","metaTitle":"DSC1122CE5-048.0020 – 48.002 MHz LVPECL MEMS Oscillator","metaDescription":"DSC1122CE5-048.0020 from Microchip Technology: XO (Standard) LVPECL output, 48.002 MHz, ±10 ppm stability, 2.25-3.6 V supply, -20 to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVPECL","Series":"DSC1122","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"48.002 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1122","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"58mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122CE5-048.0020","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CE5-048.0020 when reusing this data.
